Wood moisture content refers to the amount of water present within the wood fibers. It is an essential factor that impacts the performance, quality, and durability of wood products. When wood moisture content is too high or too low, it can lead to a range of issues, including:
– **Shrinking and swelling:** As wood dries or absorbs moisture, it undergoes dimensional changes, which can result in warping, cracking, and splitting.
– **Biological degradation:** Excessive moisture promotes the growth of mold, fungi, and insects, leading to decay and reduced structural integrity.
– **Fire resistance:** Dry wood is less flammable than wet wood, making moisture content a critical factor in fire safety.
– **Strength and stiffness:** The strength and stiffness of wood are directly affected by its moisture content. Dry wood is generally stronger and stiffer than wet wood.
